Formulation Questions Answered

Here are the answers to your formulation questions:

1. Can Fractionated Coconut Oil dissolve oil-soluble substances?
   Yes, Fractionated Coconut Oil can dissolve oil-soluble substances. It is commonly used as a carrier oil for essential oils and fragrance oils because of its ability to dissolve them.

2. What ratio of Propylene Glycol is needed to dissolve BHA (Salicylic Acid)?
   Propylene Glycol can dissolve Salicylic Acid (BHA), but its solubility is limited compared to other solvents like Isopentyldiol, which can dissolve up to approximately 25% Salicylic Acid. The amount of Propylene Glycol needed to dissolve a specific concentration of Salicylic Acid depends on the overall formula composition. For a 2% concentration of Salicylic Acid, a high percentage of Propylene Glycol may be required in the formula, potentially exceeding 50% according to some formulation practices, although the recommended usage rate for Propylene Glycol is typically 1-20% and not more than 50%. For better solubility of Salicylic Acid, consider using Isopentyldiol or other recommended solvents mentioned in the Salicylic Acid product description.
